Certain phenylhydrazone derivatives are proposed in the literature as active ingredients in pesticides. However, the biological properties of these known compounds are not entirely satisfactory in the field of pest control, which is why there is a demand for providing further compounds which have pesticidal properties, in particular for controlling insects and representatives of the order Acarina, this object being achieved according to the invention by providing the present pesticides containing compounds of the formula (I).

Some compounds of the formula (I) contain asymmetric carbon atoms, which is why optically active forms of the compounds can occur. Owing to the presence of the C═N double bond, E- and Z-isomeric forms of the compounds may occur. Moreover, atropisomers of the compounds may occur. The formula (I) is intended to embrace all these isomeric forms which are possible and mixtures of these, for example racemates or E/Z isomer mixtures.

Unless otherwise defined, the general terms used hereinabove and hereinbelow have the meanings given in the following text.

Unless otherwise defined, carbon-containing groups and compounds contain in each case 1 up to and including 8, preferably 1 up to and including 6, in particular 1 up to and including 4, especially 1 or 2, carbon atoms.

Alkyl—as a group per se and as structural element of other groups and compounds, such as of haloalkyl, alkoxy or alkylthio—is, in each case with due consideration of the number of carbon atoms present in the relevant group or compound in every single case, either straight-chain, i.e. methyl, ethyl, propyl, butyl, pentyl or hexyl, or branched, e.g. isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl, neopentyl or isohexyl.

Alkenyl—as a group per se and as structural element of other groups and compounds, such as of alkenoxy, haloalkenyl or haloalkenoxy—is, in each case with due consideration of the number of carbon atoms present in the relevant group or compound in every single case, either straight-chain, e.g. vinyl, 1-methylvinyl, allyl, 1-butenyl or 2-hexenyl, or branched, e.g. isopropenyl.

Alkynyl—as a group per se and as structural element of other groups and compounds, such as haloalkynyl—is, in each case with due consideration of the number of carbon atoms present in the relevant group or compound in every single case, either straight-chain, e.g. propargyl, 2-butynyl or 5-hexynyl, or branched, e.g. 2-ethynylpropyl or 2-propargylisopropyl.

C₃-C₆-cycloalkyl is cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl.

Aryl is especially phenyl or naphthyl, in particular phenyl.

Monocyclic hetaryl has 1 up to and including 4 ring hetero atoms and is, for example, furyl, thienyl, pyridyl, imidazolyl, thiazolyl, oxazolyl, pyrimidyl, oxadiazolyl, thiadiazolyl, triazolyl or tetrazolyl.

Bicyclic hetaryl is to be understood as meaning a radical which contains 1 up to and including 4 hetero atoms either in only one ring—for example in quinolinyl, quinoxalinyl, indolinyl, benzothiophenyl or benzoturanyl—or in both rings—for example in pteridinyl or purinyl, the hetero atoms being independent of one another.

Halogen—as a group per se and as structural element of other groups and compounds, such as haloalkyl, haloalkenyl, haloalkynyl and haloalkoxy—is fluorine, chlorine, bromine or iodine, in particular fluorine, chlorine or bromine, especially fluorine or chlorine, very particularly chlorine.

Halogen-substituted carbon-containing groups and compounds, such as haloalkyl, haloalkenyl or haloalkynyl, can be partially halogenated or perhalogenated, it being possible for the halogen substituents to be identical or different in the case of polyhalogenation. Examples of haloalkyl—as a group per se and as a structural element of other groups and compounds, such as haloalkenyl—are methyl which is mono- to trisubstituted by fluorine, chlorine and/or bromine, such as CHF₂ or CF₃; ethyl which is mono- to pentasubstituted by fluorine, chlorine and/or bromine, such as CH₂CF₃, CF₂CF₃, CF₂CCl₃, CF₂CHCl₂, CF₂CHF₂, CF₂CFCl₂, CF₂CHBr₂, CF₂CHClF, CF₂CHBrF or CClFCHCIF; propyl or isopropyl, each of which is mono- to heptasubstituted by fluorine, chlorine and/or bromine, such as CH₂CHBrCH₂Br, CF₂CHFCF₃, CH₂CF₂CF₃ or CH(CF₃)₂; and butyl or an isomer thereof which is mono- to nonasubstituted by fluorine, chlorine and/or bromine, such as CF(CF₃)CHFCF₃ or CH₂(CF₂)₂CF₃. Haloalkenyl is, for example, CH₂CH═CHCl, CH₂CH═CCl₂, CH₂CF═CF₂ or CH₂CH═CHCH₂Br. Haloalkynyl is, for example, CH₂C≡CF, CH₂C≡CCH₂Cl or CF₂CF₂C≡CCH₂F.

Those skilled in the art will be familiar with the fact that some compounds of the formula (I) can exist as tautomers, particularly when R₂ is H. The compounds of the formula (I) are therefore also to be understood as meaning, hereinabove and hereinbelow, the relevant tautomers, even when the latter are not mentioned specifically in each individual case.

Compounds of the formula (I) which have at least one basic centre can form, for example, acid addition salts. These acid addition salts are formed for example with strong inorganic acids, such as mineral acids, e.g. perchloric acid, sulfuric acid, nitric acid, nitrose acid, a phosphorus acid or a hydrohalic acid, with strong organic carboxylic acids, such as C₁-C₄alkanecarboxylic acids which are unsubstituted or substituted, for example by halogen, e.g. acetic acid, such as saturated or unsaturated dicarboxylic acids, e.g. oxalic, malonic, succinic, maleic, fumaric or phthalic acid, such as hydroxycarboxylic acids, e.g. ascorbic, lactic, malic, tartaric or citric acid, or such as benzoic acid, or with organic sulfonic acids, such as C₁-C₄alkanoic or arylsulfonic acids which are unsubstituted or substituted, for example by halogen, e.g. methane- or p-toluenesulfonic acid. Furthermore, compounds of the formula (I) which have at least one acidic group can form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal or alkaline earth metal salts, e.g. sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower-alkylamine, e.g. ethyl-, diethyl-, triethyl- or dimethylpropylamine, or with a mono-, di- or trihydroxy-lower-alkylamine, e.g. mono-, di- or triethanolamine. If appropriate, corresponding internal salts may furthermore be formed. Because of the close relation between the compounds of the formula (I) in free form and in the form of their salts, the free compounds of the formula (I) or salts thereof are to be understood as meaning, hereinabove and hereinbelow, in the spirit and for the purposes of the present invention, the corresponding salts or the free compounds of the formula (I), if so appropriate. The same applies to tautomers of compounds of the formula (I) and the salts of these tautomers. In general, the free form is preferred in each case.

Examples of such solvents or diluents which may be mentioned are: aromatic, aliphatic and alicyclic hydrocarbons and halohydrocarbons such as benzene, toluene. xylene, mesitylene, tetralin, chlorobenzene, dichlorobenzene, bromobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, tetrachloromethane, dichloroethane, trichloroethene or tetrachloroethene; ethers such as diethyl ether, dipropyl ether, diisopropyl ether, dibutyl ether, tert-butyl methyl ether, ethylene glycol dimethyl ether, dimethoxydiethyl ether, tetrahydrofuran or dioxane; and nitrites such as acetonitrile or propionitrile.

Thioethers which are preferably added are dialkyl thioethers, especially diethyl sulfide or dimethyl sulfide, preferably dimethyl sulfide.

The reaction is advantageously carried out in a temperature range of from approximately 0° C. to approximately −100° C., especially at −50 to −80° C., preferably at approximately −60° C.

The reaction is preferably carried out under atmospheric pressure.

The reaction can be carried out without a protective gas atmosphere; however, it is preferably carried out under a protective gas atmosphere, e.g. nitrogen or argon, in particular nitrogen.

The reaction time is not critical; preferred is a reaction time of from approximately 0.1 to approximately 24 hours, in particular from approximately 3 to approximately 6 hours.

The product is isolated by customary methods, e.g. by filtration, crystallization, distillation or chromatography, or any suitable combination of these processes.

The compounds of the formulae (I), (II) and (VIII) can be in the form of one of the isomers which are possible or as a mixture of these, for example depending on the number, absolute and relative configuration of the asymmetric carbon atoms, as pure isomers such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures; the invention relates to the pure isomers and also to all isomer mixtures which are possible and is to be understood hereinabove and hereinbelow in each case in this sense even when stereochemical details are not mentioned specifically in each case.

Diastereomer mixtures and racemate mixtures of compounds of the formulae (I), (II) and (VIII) which can be obtained in accordance with the process—depending on the choice of starting materials and procedures—or by other means can be resolved into the pure diastereomers or racemates in the known manner on the basis of the physico-chemical differences of the components, for example by fractional crystallization, distillation and/or chromatography.

Enantiomer mixtures which can be obtained accordingly, such as racemates, can be separated into the optical antipodes by customary methods, for example by recrystallization from an optically active solvent, by chromatography on chiral adsorbents, for example high-performance liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable microorganisms, by cleavage with specific immobilized enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer is complexed.

In addition to separating appropriate isomer mixtures, pure diastereomers or enantiomers can also be obtained in accordance with the invention by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process according to the invention with starting materials of a suitable stereochemistry.

It is advantageous to isolate, or synthesize, in each case the biologically more effective isomer, for example enantiomer, or isomer mixture, for example enantiomer mixture, if the individual components have different biological activity.

The compounds of the formulae (I), (II) and (VIII) can also be obtained in the form of their hydrates and/or include other solvents, for example, if desired, those which have been used for crystallizing compounds in solid form.

The invention relates to all those embodiments of the process which start from a compound which can be obtained as starting material or intermediate at any level of the process and where all or some of the missing steps are carried out or where a starting material is used in the form of a derivative or salt and/or the racemates or antipodes thereof or, in particular, such a starting material is formed under the reaction conditions.

Starting materials and intermediates which are preferably used in the process of the present invention are those which lead to the compounds of the formula (I) which have been described at the outset as being particularly valuable.

In particular, the invention relates to the preparation processes described in Examples H5, H6, H7, H8 and H10.

The invention also relates to starting materials and intermediates used for the preparation of the compounds of the formula (I), in particular to those compounds of the formulae (II) and (VIII), which are novel, and to their use and processes for their preparation. The compounds of the formulae II and VIII, in particular, can be prepared analogously to Examples H1 and H3, respectively.

Those compounds of the formulae (III) to (VII) and (IX) which are not already known can be prepared by processes known per se.

The invention furthermore relates to a method of controlling pests using a compound of the formula (I), in which A₁, A₂, R₁ and R₂ are as indicated above for formula (I), with the exception of 1-phenylhydrazono-2-nitriloethylbenzene.

The compounds of the formula (I) according to the invention are preventively and/or curatively valuable active ingredients in the field of pest control, even at low rates of concentration, which have a very favourable biocide spectrum and are well tolerated by warm-blooded species, fish and plants. The term pests first of all includes in the frame of the present invention insects, representatives of the order Acarina, microorganisms, and representatives of the classes Nematoda and Trematoda; especially insects, representatives of the order Acarina and phytopathogenic fungi, more particularly insects and representatives of the order Acarina. The active ingredients according to the invention are effective against all or individual developmental stages of normally sensitive, but also resistant, animal pests such as insects and representatives of the order Acarina. The insecticidal, ovicidal and/or acaricidal activity of the active ingredients according to the invention can manifest itself directly, i.e. in mortality of the pests, which takes place immediately or only after some time has elapsed, for example during ecdysis, or of their eggs, or indirectly, for example in a reduced oviposition rate and/or hatching rate, the good activity corresponding to a mortality rate (mortality) of at least 50 to 60%.

The activity of the compositions comprising the compounds of the formula (I) and of the compounds of the formula (Ia) can be substantially broadened and adapted to prevailing circumstances by the addition of other insecticides and/or acaricides. Examples of suitable additional active ingredients include representatives of the following classes of compounds: Thioureas, benzoylureas, carbamoyloximes, halogated carboxylic acid derivatives, organophosphates, organochloro derivatives, nitroenamines, nitroguanidines, cyanoguanidines, carbamates, thiocarbamates, carbodiimides, formamidines, benzilic acid derivatives, dioxolanes, thiadiazinderivatives, unsymmetrical triazines, symmetrical triazines, pyridazinones, pyrroles, phenoxyphenylethers, sulfonic acid amides, Bacillus thuringiensis-preparations, milbemycines, avermectines and pyrethroids.

The active ingredients according to the invention can be used for controlling, i.e. containing or destroying, pests of the abovementioned type in particular on plants, mainly on crops of useful plants and ornamentals in agriculture, in horticulture and in silviculture, or on parts of such plants, such as fruits, flowers, foliage, stalks, tubers or roots, and in some cases even parts of plants which are formed at a later point in time are afforded protection against these pests

Target crops which are suitable are, in particular, cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar or fodder beet; fruit, e.g. pomaceous fruit, stone fruit and soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soya; oil crops, such as oilseed rape, mustard, poppies, olives, sunflowers, coconut, castor, cocoa or groundnuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruits or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or bell peppers; the laurel family, such as avocado, Cinnamonium, or camphor; and also tobacco, nuts, coffee, egg plants, sugar cane, tea, pepper, grapevines, hops, the plantain family, latex plants and ornamentals.

The active ingredients according to the invention are especially suitable for controlling insects and representatives of the order Acarina, in particular feeding insects which damage plants, such as Anthonomus grandis, Diabrotica balteata, Heliothis virescens larvae, Plutella xylostella and Spodoptera littoralis larvae, and spider mites such as Tetranychus spp. in cotton, fruit, maize, soya, oilseed rape and vegetable crops.

Other fields of application of the active ingredients according to the invention are the protection of stored products and stores and of material, and, in the hygiene sector, in particular the protection of domestic animals or productive livestock against pests of the abovementioned type.

The invention therefore especially relates to a pesticidal composition which comprises a compound of the formula (I), with the exception of 1-phenylhydrazono-2-nitriloethylbenzene, in the form of emulsifiable concentrates, suspension concentrates, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, wettable powders, soluble powders, dispersible powders, wettable powders, dusts, granules or encapsulations in polymeric substances, all of which comprise—at least—one of the active ingredients according to the invention and which are to be selected to suit the intended aims and prevailing circumstances.

In these compositions, the active ingredient is employed together with—at least—one of the auxiliaries conventionally used in the art of formulation, such as extenders, e.g. solvents or solid carriers, or such as surface-active compounds (surfactants).

Examples of suitable solvents are: non-hydrogenated or partially hydrogenated aromatic hydrocarbons, preferably the fractions C₈ to C₁₂ of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons such as paraffins or cyclohexane, alcohols such as ethanol, propano) or butanol, glycols and their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methylpyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, free or epoxidized rapeseed, castor, coconut or soya oil, and silicone oils.

Solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silicas or highly-disperse absorptive polymers. Suitable particulate adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are calcite or sand. Moreover, a large number of granulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues.

Suitable surface-active compounds are, depending on the nature of the active ingredient to be formulated, non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties. The surfactants listed below are only to be considered as examples; many more surfactants conventionally used in the art of formulation and suitable in accordance with the invention are described in the relevant literature.

Suitable non-ionic surfactants are primarily polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, of saturated or unsaturated fatty acids and alkylphenols which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenots. Also suitable are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbons in the alkyl chain and 20 to 250 ethylene glycol ether and 10 to 100 propylene glycol ether groups. The above-mentioned compounds normally contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenylpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypoiyethoxyethanol. Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.

The cationic surfactants are mainly quaternary ammonium salts which have, as substituents, at least one alkyl radical of 8 to 22 carbon atoms and, as further substituents, lower alkyl, benzyl or lower hydroxyalkyl radicals which may be halogenated. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples are stearyltrimethylammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide.

Suitable anionic surfactants can be both water-soluble soaps and water-soluble synthetic surface-active compounds. Soaps which are suitable are the alkali metal salts, alkaline earth metal salts and unsubstituted or substituted ammonium salts of higher fatty acids (C₁₀-C₂₂), such as the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which can be obtained, for example, from coconut or tall oil; mention must also be made of the fatty acid methyltaurinates. However, synthetic surfactants, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates, are used more frequently. As a rule, the fatty sulfonates and fatty sulfates exist as alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and generally have an alkyl radical of 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals: examples which may be mentioned are the sodium or calcium salt of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared with natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfo groups and one fatty acid radical having approximately 8 to 22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensate. Also suitable are corresponding phosphates, such as salts of the phosphoric ester of a p-nonylphenol(4-14)ethylene oxide adduct, or phospholipids.

As a rule, the compositions comprise 0.0000001 to 99.99%, especially 0.1 to 99%, in particular 0.1 to 95%, of active ingredient and 0.01 to 99.9999999%, especially 1 to 99.9%, in particular 5 to 99.9%, of—at least—one solid or liquid auxiliary, it being possible, as a rule, for the surfactants to amount to 0 to 25%, in particular 0.1 to 20%, of the composition (% is in each case per cent by weight). While concentrated compositions are more preferred as commercially available goods, the end user uses, as a rule, dilute compositions, which have a considerably lower concentration of active ingredient. Preferred compositions are composed in particular as follows (%=percent by weight):

Emulsifiable concentrates:

active ingredient: 1 to 90%, preferably 5 to 20%

surfactant: 1 to 30%, preferably 10 to 20%

solvent: 5 to 98%, preferably 70 to 85%

Dusts:

active ingredient: 0.1 to 10%, preferably 0.1 to 1%

solid carrier: 99.9 to 90%, preferably 99.9 to 99%

Suspension concentrates:

active ingredient: 5 to 75%, preferably 10 to 50%

water: 94 to 24%, preferably 88 to 30%

surfactant: 1 to 40%, preferably 2 to 30%

Wettable powder:

active ingredient: 0.5 to 90%, preferably 1 to 80%

surfactant: 0.5 to 20%, preferably 1 to 15%

solid carrier: 5 bis 99%, vorzugsweise 15 bis 98%

Granules:

active ingredient: 0.5 to 30%, preferably 3 to 15%

solid carrier: 99.5 to 70%, preferably 97 to 85%

The activity of the compositions according to the invention can be widened considerably, and adapted to prevailing circumstances, by adding other insecticidally, acaricidally and/or fungicidally active ingredients. Examples of suitable additives of active ingredients are representatives of the following classes of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis peparations. The compositions according to the invention may also comprise other solid or liquid auxiliaries such as stabilizers, for example epoxidized or unepoxidized vegetable oils (e.g. epoxidized coconut oil, rapeseed oil or soya oil), antifoams, e.g. silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, and also fertilizers or other active ingredients for achieving specific effects, for example bactericides, nematicides, molluscicides or selective herbicides.

The compositions according to the invention are prepared in a known manner, in the absence of auxiliaries for example by grinding and/or screening a solid active ingredient, or active ingredient mixture, for example to obtain a specific particle size, and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the active ingredient, or active ingredient mixture, with the auxiliary (or auxiliaries). These processes for the preparation of the compositions according to the invention and the use of the compounds of the formula (I) for the preparation of these compositions are also subjects of the invention.

The methods of application for the compositions, i.e. the methods of controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, seed-dressing, scattering or pouring, which are to be selected to suit the intended aims and the prevailing circumstances, and the use of the compositions for controlling pests of the abovementioned type are also subjects of the invention. Typical use concentrations are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The rates of application per hectare are generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 20 to 600 g/ha.

A preferred method of application in the field of crop protection is application to the foliage of the plant (foliar application), it being possible to adjust frequency and rate of application to the degree or risk of infestation with the pest in question. Alternatively, the active ingredient can reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example in the soil, for example in the form of granules (soil application). In the case of paddy rice crops, such granules can be metered into the flooded paddy field.

The compositions according to the invention are also suitable for the protection of plant propagation material, e.g. seed such as fruits, tubers or kernels, or nursery plants, against fungal infection and animal pests. The propagation material can be dressed with the composition before planting, for example seed can be dressed before sowing. It is also possible to apply the active ingredients according to the invention to seed kernels (coating), either by soaking the kernels in a liquid composition or by coating them with a solid composition. Alternatively, the composition can be applied to the site of application when the propagation material is planted, for example into the seed furrow during sowing. These treatment methods for plant propagation material and the plant propagation material treated accordingly are further subjects of the invention.

The examples which follow are intended to illustrate the invention. They do not limit the invention. Temperatures are given in degrees Celsius.

Example H5 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]-2-nitriloethyl}benzonitrile

55 g of solid 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]chloromethyl}benzonitrile are added in portions in the course of approximately one hour to 11.4 g of sodium cyanide in 270 ml of water and 400 ml of ethanol. After the mixture has been stirred for three hours at room temperature, 200 ml of ethanol and 135 ml of water are added and the mixture is stirred for a further 5 hours. 100 ml of water are added slowly, the precipitate is filtered off and washed with water, and the filter residue is dried in vacuo at 40°. This gives the title compound of melting point 186-187° (compound no. 3.4).

Example H6 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]-2-nitriloethyl}chlorobenzene

a) 1.5 g of sodium nitrite are added at room temperature to a mixture of 14 ml of concentrated sulfuric acid and 14 ml of acetic acid. The mixture is heated to 80° and stirred until all solids have dissolved, and the solution is cooled to room temperature. To this mixture there are added 4.6 g of 2,6-dichloro-4-trifluoromethylaniline, dissolved in 14 ml of concentrated sulfuric acid, and the mixture is stirred for one hour at room temperature and then for one hour at 50°.

b) The solution prepared in accordance with a) is added with stirring at room temperature to 3.85 g of 3-oxo-2-(4-chlorophenyl)butyronitrile in 28 ml of acetic acid and 40 ml of water, and the mixture is stirred for a further three hours. The mixture is poured into 300 ml of ice-water and extracted three times using in each case 100 ml of ethyl acetate. The combined organic phases are washed with water, dried over sodium sulfate and evaporated to dryness in vacuo. The residue is crystallized from toluene/hexane 1:1. This gives the title compound of melting point 164-165° (compound no. 3.16).

Example H7 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)methylhydrazono]-2-nitriloethyl}benzonitrile

To 0.96 g of 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]-2-nitriloethyl}benzonitrile in 30 ml of ethyl methyl ketone there are added 0.7 g of finely pulverized potassium carbonate and 1.4 g of methyl iodide. The mixture is heated to 80° and stirred for three hours. The reaction mixture is filtered, the filtrate is concentrated in vacuo, and the residue is dissolved in ethyl acetate. The ethyl acetate phase is washed with water and NaCl solution, dried over sodium sulfate and evaporated to dryness in vacuo. After the residue has been washed with hexane, the title product of melting point 92-93° is obtained (compound no. 3.29).

Example H8 methyl{N′-[1-(4-cyanophenyl)-2-nitriloethylidene]-N-(2,6-dichloro-4-trifluoromethylphenyl)hydrazino]oxoacetate

0.73 g of potassium tert-butoxide is added to 1.9 g of 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]nitrilomethyl}benzonitrile in 40 ml of anhydrous tetrahydrofuran. A solution of 0.8 g of methyl chlorooxalate in 5 ml of tetrahydrofuran is added dropwise at 10° and the mixture stirred for 2 hours. The reaction mixture is evaporated to dryness, the residue is taken up in ethyl acetate, and the organic phase is washed with water and dried over sodium sulfate. The solvent is evaporated and the residue is chromatographed on silica gel using n-hexane/diethyl ether (3:1) as the eluent. This gives the title product of melting point 194-195° (compound no. 3.36).

Example H10 4-{1-[(2-chloro-4-trifuoromethylphenyl)hydrazono]-2,2,2-trifluoroethyl}chlorobenzene

3.15 g of 2-chloro-4-trifluoromethylphenylhydrazine, 3.75 g of 2′,2′,2′-trifluoro-4-chloroacetophenone, 60 ml of anhydrous ethanol and 0.2 ml of glacial acetic acid are heated for two days in a water separator. The mixture is poured into 300 ml of ice-water and extracted three times using in each case 100 ml of ethyl acetate. The combined organic phases are washed with water, dried over sodium sulfate and evaporated to dryness in vacuo. The residue is crystallized from toluene/hexane 1:1. This gives the liquid title compound; n_(D) ²⁰: 1.5390 (compound no. 5.2).
